Outline and tips
Tadalafil is the active ingredient in medicines often marketed as Cialis. It belongs to a class called phosphodiesterase type 5 inhibitors (PDE5 inhibitors) and works by increasing blood flow to the penis during sexual stimulation to help achieve and maintain an erection.
In the UK, the main licensed indication for tadalafil is erectile dysfunction in adult males. Depending on the product and dose, tadalafil is also used for benign prostatic hyperplasia and, in other formulations or under other brand names, for pulmonary arterial hypertension. A qualified prescriber will decide the appropriate indication and dosage.

- Recent heart attack (within the last 90 days), unstable angina, severe heart failure or serious arrhythmias.
- Blood pressure that is either very high or very low.
- Severe hepatic dysfunction or renal impairment, including dialysis.
- Illustrative blood disorders include sickle cell disease, leukemia, and multiple myeloma.
- Active stage of peptic ulcer disease or bleeding disorders.

Some mutual interactions create opportunities for collaboration. with tadalafil can be serious. The most dangerous combination is with nitrate medicines or nitric oxide donors; this can cause a severe fall in blood pressure.

- Strong CYP3A4 inhibitors that increase tadalafil concentrations: ketoconazole, itraconazole, ritonavir, cobicistat, clarithromycin and similar agents.
- CYP3A4 inducers that reduce tadalafil exposure and may lower effectiveness: rifampicin, rifabutin, carbamazepine, phenytoin, phenobarbital and Hypericum perforatum plant.
- Alpha-blockers such as doxazosin, alfuzosin or tamsulosin which together with tadalafil can cause symptomatic low blood pressure; careful timing and health monitoring are required.
- Certain calcium channel blockers like diltiazem or verapamil which may interact on heart rate and blood pressure.
- Other potential interactors include bosentan, cimetidine and some antiarrhythmics such as quinidine formulations.
